Obesity is a major risk factor for premature arterial abnormalities including high blood pressure and increased stiffness. Previous studies have shown that weight loss via lifestyle modifications is associated with a decrease in large artery (aorta) stiffness. However, along with decreases in fat mass, hypocaloric diet reduces muscle mass. Whole body vibration results in similar increases in muscle mass and strength than those observed after resistance exercise and is feasible for special populations such as the obese and the elderly.
